Detectives from the Port Philip Criminal Investigation Unit are requesting public assistance following an aggravated robbery in South Melbourne last month.
It is understood that a man entered a property on Coventry Street at around 2:40am on Thursday March 24 while the occupants were asleep.
Detectives were told a male victim woke up to find the offender and escorted him out of the building.
The offender then fled the scene and there were no injuries.
Investigators have released a digital image of a man and CCTV footage in the hope someone might recognize him.
The man is described as Caucasian, in his 40s with short brown hair.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or make a report at www.crimestoppersvic.com.auexternal link.
